Fire onbeforeunload confirm alert for external sites only

Question

I am using window.onbeforeunload method to show confirm message if user leaves website.

window.onbeforeunload = function(e) {
    return textMsg;
};

But I need this to be fired only if user navigates to external web-site or closes window.

So how to cancel this confirm message for all XHR inside same domain and form submit etc?

Try (untested code):

window.onbeforeunload = function(e) {
    return textMsg;
};

$('a:not([href^="http"])').on('click', function() {
    window.onbeforeunload = null; // prevent message
});

$('form').on('submit', function() {
    window.onbeforeunload = null; // prevent message
});

This will prevent the event from triggering if links do not start with http (external links) and for <form> submits. Looking for a solution for window closing at the moment.

how about using window.location? It should't appear too. – vickk Apr 02 '15 at 08:56
What would you do with it? – D4V1D Apr 02 '15 at 08:57
I am using both links and window.location to redirect to response url. And If I select elements byTagName , then href method returns full url with http – vickk Apr 02 '15 at 09:08
the solution works. But is there any way to cancel popup on page refresh too? – vickk Apr 02 '15 at 10:51
Thanks, solution helped.In the end we skipped detecting browser refresh – vickk Apr 04 '15 at 06:18
